Ocz Pc5000

CaptainComputer · 05-10-2005, 11:32 PM

Just got a pair of OCZ 512MB PC5000 for my Abit IC7. Thought I'd share my results. Although they're supposed to be able to hit 600MHz-625MHz at 3-4-4 there is no way I can get my 3.0GHz CPU to run at 4.5GHz to find out.

So instead I went for the lowest latencies possible.
The best I could get is 272MHz FSB (4.08GHz@1.4125v) 2.5-3-3-1T. Sisoft Sandra results 6518/6529.

A definite improvement over my older OCZ PC4400.

I know my CPU can get to 4.15GHz but I'd have to increase the memory latencies. I'll experiment some more when I get some time.

What voltage do you need to run the RAM at to achieve 272MHz FSB at 2.5-3-3-1T? What chips do they have?

Thanks for sharing!

I think the OCZ PC5000 stuff is tccd. Which means the voltage is probably less than 3.0 but I could be wrong.

Cap'n that's awesome. I think you're right: the 4.08 should be faster than 4.15
I need a 3.0 that can do that kind of speed. Is it a 30 capper?

My CPU is a Prescott DO but I can't remember it it's a 30 capper, however I did lap the CPU before installing it.
My DDR voltage is 2.8v the max my IC7 board can do.

CaptainComputer, I'm running a 3.0c @ 3.6 & want new memory so hopefully you can help me with my choice

Am I better off running 1:1 @ 2-2-2 or 3-2-2 or with higher latencies and the divider set to for my memory to reach DDR600 speeds? The cost difference is about $100 or so, is it worth spending more?

Thanks for any advice you can give!

Since you have a prescHott can't you use the 14x multi? I bet that would allow you to go faster on the FSB at 1:1 and get a bit more speed from the RAM.

In answer to your question

Your always better off getting the most overclock out of your CPU first. To find your CPU's OC limit first underclock your RAM so that it's out of the equation. Keep raising the FSB until you find the most stable point for your CPU. Once you know what the max FSB for your CPU is, then you can make a better decision as to which memory to buy. Currently no memory can do better than 3-4-4 at 600+MHz. The OCZ PC-5000 can do 2.5-3-3 at 550MHz.

Although 14X is theoretically possible on the 3.0 no BIOS supports it. Some steppings of the Prescott 3.2 + 3.4 can be lowered to 14X on some boards that support the LockFree feature. If there was a way to use Intel SpeedStep technology on any other Prescotts I'd sure love to know.

jmichaelp · 05-14-2005, 05:27 PM

Thanks for the reply captaincomputer. I'm at my most stable now, 240fsb. I can either run 1:1 2-2-2-/3-2-2 at this speed or 4:5 3-4-4 with the higher speed ram for $100 or so more. So, is it worth the extra $.

I'm an idiot, I replied before my coffee fully kicked in. I thought you had a 3.2e. My mistake.
